The Hilbert transform (and its inverse) are the integral
transform
where the Cauchy principal value is taken in each of the integrals. The Hilbert transform is an improper
integral.
They will be implemented in a future version of the Wolfram Language as HilbertTransform[f, x, y] and InverseHilbertTransform[g,
y, x], respectively.

hypergeometric function of the first kind.
